4.5 Uncertainty

1) Radiated disturbances from 30 MHz to 1000 MHz at a distance of 3 m and 10 m Expanded

Uncertainty

U = k * Uc(xi) = 2 * 2.10 = 4.20 dB

The coverage factor k =2 yields approximately a 95% level of confidence. 2) Conducted disturbance from 150 KHz to 30 MHz using a 50 Ω/50 μH AMN Expanded

uncertainty

U= k * Uc(xi) = 2 * 1.57 = 3.14dB

The coverage factor k =2 yields approximately a 95% level of confidence.

※ When the measured emission is positioned within the range of the uncertainty of measurement

from the emission limit, the uncertainty of measurement shall be concerned as follow.

Compliance or non-compliance with a disturbance limit shall be determined in the following manner.

If Ulab is less than or equal to Ucispr

- Compliance is deemed to occur if no measured disturbance exceeds the disturbance limit;

- Non-compliance is deemed to occur if any measured disturbance exceeds the disturbance limit.

If Ulab is greater than Ucispr

- Compliance is deemed to occur if no measured disturbance, increased by (Ulab - Ucispr), exceeds

the disturbance limit;

- Non-compliance is deemed to occur if any measured disturbance, increased by (Ulab - Ucispr),

exceeds the disturbance limit.

※ If the measurement value is lower or equal to the limit, the EUT is considered to pass the test.

5. Test Results EMISSION 5.1 Conducted Disturbance at mains terminals

Result PASS

Temperature 21 ℃ Test Environment Humidity 24 % R.H.

Test Procedure

The line-conducted facility is located inside a 2.6 m x 3.6 m x 7.0 m shielded room. The shielding effectiveness of the shielded room is in accordance with MIL-Std-285 or NSA 604-05. A wooden table with 80 cm height is placed 40 cm away from the vertical conducting plane and 1.5 m away from the other side of the shielded room. A Line Impedance Stabilization Network(LISN) that provided a 50ohm/ 50µH coupling impedance are bonded to the shielded room. The EUT was connected to the mains power through a LISN that provided a 50 ohm/ 50 µH coupling impedance for the measuring instrument and the ancillary equipment was also connected to the mains power through the LISN that provided a 50 ohm/ 50 µH coupling impedance with 50 ohm termination. The EMI test receiver was set to frequency range from 150 kHz to 30 MHz and bandwidth at 10 kHz and detector as Quasi-Peak or Average. The AC power line conducted emission was measured between each power line and ground at the power terminal. The initial testing identified the frequency that has the highest emission relative to the limits while operating the EUT in typical modes of operation and cable positions in a test setup representative of typical system configuration. The identification of the frequency of highest emission with respect to the limit was found by investigating emissions at a number of significant frequencies. The probable frequency of maximum emission had been found and that the associated cable and EUT configuration and mode of operation had been identified.

5.2 Radiated Disturbance

Result PASS

Temperature 18 ℃ Test Environment Humidity 28 % R.H.

Test Procedure

The EUT was placed on a non-conductive table with 0.8 m height. The turntable

can rotate 360 degree to determine the position of the maximum emission level.

The EUT was set 10 meters away from the receiving antenna that was mounted

on a non-conductive master. The antenna can move up and down between 1 to 4

meters to find out the position of the maximum emission level. The floor of the

Open Area Test Site(OATS) is covered by a conductive metal ground plane and

OATS comply with the Normalized Site Attenuation requirements. The spectrum

was scanned from 30 to 1000 MHz using Trilog-Broadband Antenna. Above 1

GHz, linearly polarized double ridge horn antennas were used.

The initial testing identified the frequency that has the highest emission relative to

the limits while operating the EUT in typical modes of operation and cable

positions in a test setup representative of typical system configuration.

The identification of the frequency of highest emission with respect to the limit was

found by investigating emissions at a number of significant frequencies. The

probable frequency of maximum emission had been found and that the associated

cable and EUT configuration and mode of operation had been identified.
